which I've never understood why they do it. If you look at the pentroofs, you can tell that standard mandrel bending is going to be impossible. so why now flare the tubing and seat one end into the other, then lap-weld it? It's stronger, truer and resists heat strains better.
but i digress. I am unemployeed. have never worked for pentroof. So all I can really do is ask questions. So, which is the best glow in the dark shift knob that shifst in a T position instead of an H position. TIA!
